The Garmin Varia RTL515 has improved my overall feeling of safety on the road ever since I turned it on. It has a very bright light that is easily seen by motorists. The radar is great at picking up traffic coming up from behind and it will notify you on your had unit and start blinking to make motorists aware of your position. I would 100% buy this product again based on how helpful it is in ensuring safety.
When I saw the price drop, I decided to finally take the plunge and buy this. I have mine paired with my Edge 1040 and I am honestly amazed at how well this works. You can easily see when cars are behind you, how many there are, and also get a sense of how close they are. As soon as it senses a car, you get a beep and a red gradient overlay appears on the sides of my Edge, along with dots on the right side showing how many cars, relative spacing between them, and how close they are to you. If the car turns off before it passes you, the red gradient overlay turns green and then fades away. It's a very simple, intuitive and effective interface, that really doesn't take anything away from your normal display. I really regret not buying this a couple of years ago! Highly recommended.
I've been on the fence about getting these, but decided to bite the bullet knowing they were almost likely to get more expensive. And I really should have gotten them sooner! Integration with the head unit is seamless (Edge 540), display is clear and intuitive without overloading me with information. Not many false positives (reading cars that weren't there) and no false negatives (missing cars that were). Bonus: It does a great job of picking up smaller vehicles (other bikes, scooters) that come up quickly. Light is really bright and I have no doubt it is really easy to spot.
The only thing I wouldn't use this for is my commute--it would just be going off non-stop while I ride through the city and I'm not sure the warning would outweigh the noise.
If you have a saddle bag that potentially obstructs the radar function, I'd suggest getting a mount that affixes itself to your saddle bag and maybe a protective case and lanyard to attach to the seat rails for extra peace of mind. Surprised Garmin doesn't at least provide the saddle bag mount as standard.
I've been road riding with one of these for close to 20,000 miles and it has been nearly flawless. I ride a mix of city streets, county highways, and desert single lane roads. The radar gives me a much better sense of surrounding traffic than would a combination of hearing and head-turning. False-positives are rare and seem to happen when turning right at intersections. Missed cars are extremely rare, but the RTL515 is still not a substitute for looking over your shoulder when changing lanes or passing parked vehicles.
I'm using the RTL515 with a Garmin 530 Edge unit. The dot and colored band on the side of the screen works well and is easy to see in your periphery vision or a quick glance down. It's not like you're reading a number or deciphering data to see that a car is gaining on you. It's simple and safe.
My RTL515 is a few years old, but as far as I can tell it still uses a USB Micro cable. This is literally my only gripe. USB-C is easier to use and should last longer.
After observing my friend using his Varia radar light, I had him hook my Garmin Edge to his light and got to experience first hand as long as I stayed close to him. My wife asked what I wanted for Christmas and the deal was done. Installed easily, but then had to learn a few things as the pictograph directions are sketchy. Luckily my buddy knows all about it. I especially enjoy that if one is not paying close attention it will chime and let you know another bike is coming up faster than you are.

In my opinion this is the best situational awareness purchase I've made for cycling. It talks directly to my Garmin 840 and has tracked up to 5 targets at a time so far. I have a mount on each of my bikes so transfer from one to another is easy. I recommend it to everyone I talk to.
Have been using an RTL510 for 6-8 months, now won't ride without it. Useful in ways I hadn't imagined: (a) on fast descents when it's too dangerous to look back, it tells you if traffic is coming up behind you, (b) tells you if it's safe to move left to avoid bad pavement, (c) if you need to turn left, it helps you tell if a clot of traffic is approaching from behind, (d) while it doesn't display the lateral position of a vehicle passing you, you should expect a close pass if it shows that a pass is happening close to a blind corner or crest, or oncoming traffic. Also, I was unaware that its flash rate increases when traffic is approaching from behind until one day in my car I came up behind a RTL-equipped cyclist - quite a light show!
Limitations: (a) in high-traffic areas it will alert continuously (I avoid areas like that anyway), (b) if you are cycling along a secondary road paralleling an expressway, it may pick up traffic on the highway, (c) on curvy or rolling roads, terrain may block the radar beam long enough for a contact to be temporarily lost, reappearing as it gets closer. You should double-check with a head turn when it's important, because the RTL gives a low rate of false positives (not critical) and a lower rate of false negatives (critical!) in certain specific situations. The false positives seem to be triggered by motion-detecting lights or cameras (I routinely get false alerts when passing certain facilities). Occasionally it may temporarily show multiple dots when there is only a single vehicle, or "miss" a vehicle following closely behind another. False negatives happen when an upcoming vehicle slows to wait for a safe opportunity to pass me, so that it is going at my speed, no longer approaching me. If that situation persists long enough, that vehicle may vanish from my screen, making an abrupt left turn risky. Have gotten these false negs a number of times.
All in all, the RTL is a huge plus, greatly reducing the amount of shoulder-checking I have to do, so I wobble less and scan the road ahead more closely.
I have been using the earlier version of Varia Radar 2 for a bit over two years. I have been told by drivers, among them two FedEX drivers, that it is the most effective tail light they have ever seen. It was visible at a distance of more than a mile. It begins flashing as soon as a car comes within the radar range. I ride just about every day and I have never been surprised by a vehicle coming up behind me. My computer beeps and the display of the vehicle or vehicles approaching shows along the right side of my Edge 1030. I can judge the speed and distance of the approaching vehicle from the display. It really is a remarkable piece of equipment, and it sounds like they have made it even better. My unit will start giving me a low battery warning after about 4 hours on a ride. I have never run out of battery, but my rides don't usually last longer than 4 hours. The longer life battery is certainly not a waste. To give some idea of the sensitivity of the radar, I was once standing by the side of the road taking a break when a runner I had passed earlier approached. The computer beeped, and the display showed the runner approaching. That is pretty amazing. Yet, at the same time, when I have ridden with another rider, his presence is not noticed by the radar, only cars approaching us. The stimulus for the radar is something approaching, not something keeping pace with you. Recharge time is about an hour or less. It is, in my opinion, a necessity if you ride on the road. It will pair with most Edge computers and, also, with Wahoo computers.
I use this on nearly every ride, unless I'm purely on singletrack, and it's been so useful for detecting traffic that I can't imagine living without it. When my first one died after years of use, I bought another one the same day. It's especially helpful on gravel roads when it's hard to hear rear approaching drivers, and it's also invaluable when riding and chatting side by side, since it saves us from having to constantly look over our shoulders. Sometimes I think that drivers should buy these for all cyclists because we probably get over so much quicker, when appropriate.
The product stays on my road bike ?? and I'm mostly a road rider in the early morning.
It's my first garmin light as I just used a led flasher previously.
Game changer that alerts you before the cars headlights do. The price was the same as years ago my buddy said.
VERY visible to drivers and the alerts are a nice touch.
The rear facing radar warns you about approaching vehicle's at a great distance. It shows dots representing approaching vehicles and has a yellow bar meaning the vehicle's are approaching at a more normal rate of speed and a red bar warnings vehicles are approaching at a rapid rate of speed. This product by no means replaces taking a look behind you before making any evasive maneuvers, but it is an added piece of mind that I greatly appreciate!
The Varia is a wonderful and, I believe, necessary addition toward safer riding. Not only are you able to have several option for the rear light, but you get a very clear image on your GPS computer of the traffic mounting behind you.
Before the Varia, I was always guessing and mostly trying to listen to what traffic was approaching. Now I have such a better sense of what my environment is like in a split second on the bike. It allows me an initial snapshot and really eases my concerns especially on single lane roads, turn left endeavors and overall solo riding. I especially love it on group rides. I now have a better idea of what is behind me while passing others and when to hug the road. Equally, no more last second "car backs" but rather a much better heads up warning.
Wish I had purchased this earlier.
I bought this after various cyclists I respect mentioned how with more electric (silent) vehicles on the road, we can all use some extra help detecting passing cars.
So far I've taken it on one ride, connected to my phone in rear pocket but I have no bike computer. So I'm relying entirely on sounds and vibration.
At first the thing was beeping non-stop for no apparent reason. I turned off "Green Level Threat Zone" which seemed to reduce the chirps to only when cars were actually nearby. But the thing still seems to err too much on the side of false positives -- ie: it seems to chirp every time I made a right turn.
Also the alerts come too soon -- cars can be hundreds of feet behind me rather than actually approaching.
I knew this when I bought it, but still disappointed that the thing won't connect to my Fitbit. Clearly an aggressive ploy to get me to buy a Garmin watch next time, which I probably will whenever my current Fitbit dies.
I didn't think I wanted or needed this, but my friend convinced me to try it. It's a game changer. The unit picks up cars well before I hear them especially on descents when wind noise blocks car sound. The display is excellent telling me the number of cars approaching and their closing speed. I love that closing speed information as I will move over as far as I can and as quickly as I can if I know a car is going really fast. A truly fantastic product.
For the past few years, I had considered purchasing the Garmin Varia' RTL515, but each time decided against it. My rationale was that I currently cycled with lights (day/night), and that the radar light combo on the Varia' RTL515 would simply be overkill. I was wrong. The first thing I noticed was that cars appeared to give me a wider birth when passing on open roads. At first, I thought it might be the placebo effect of my new tech purchase, but after several weeks of continued safe passes, I wonder if it might be something else -- the flashing pattern of the light, the possibility that driver's see the Varia' and assume it's a camera, etc? For the type of cycling that I do, the Varia' RTL515 is the ideal tool to help me keep safe. 75% of my riding is on open roads, many of which are rural. I cannot think of the time when the radar didn't detect a vehicle before I heard the vehicle. The Varia' RTL515 It tells me what's behind (displayed on my Edge 840) and adds the provided safety of a rear light. I highly recommend.
I had always seen these on other bikes and never really understood how one could justify buying such an expensive "light". After just a few rides I won't ride without this. The peace of mind I have now knowing what is coming up behind me absolutely makes this little gadget worth the price. The ability to turn the light on/off from your head unit is also an understated feature but a nice thing to have to preserve battery when you're not riding on a road.
I ride a lot of great backroads in forested countryside. At 18-20 mph It's hard to hear or see cars coming from behind so it's hard for them see me too. Rtl515 bright light and early warning radar let me be seen and ride to the side with plenty of time. Still always check over my shoulder but this added check gives me more Confidence that I don't miss anything. Great to only charge 1 instead of 2 accessories also and takes way less space than sprig and radar I used to use. . I get about 4-5 hours on a charge. Just enough for most rides.
Purchased for a planned cross country trip. I am hearing impaired and I wanted something that would help identified vehicles approaching from the rear on open roads with no shoulders in windy or noisy environments. I now have ~ 1000 miles of use on it riding solo and in a group over the past month. Works great and does exactly what I had hoped. It gives you ~ 5-7 seconds of notification when vehicles are approaching @ 50-60 mph. This is more than enough time to make any necessary adjustments to your riding. My only gripe is the Garmin Edge 1030 audible alarm isn't loud enough for me to hear (common complaint). However, using the Varia App I am able to hear the phone audio alarm (volume controllable) and feel it vibrate in my Jersey pocket. I would recommend this product for anyone who wants to be aware of vehicles approaching from behind. On a side note. It would be kind of cool if the App or your control unit kept track of the total number of vehicles that passed you. Seems like it would be easy to write the code for an easy software upgrade.
